Personality Traits Associated with Genetic Counselor Compassion Fatigue: The Roles of Dispositional Optimism and Locus of Control

Compassion fatigue (CMF) arises as a consequence of secondary exposure to distress and can be elevated in some health practitioners. Locus of control and dispositional optimism are aspects of personality known to influence coping style. To investigate whether these personality traits influence CMF risk, we surveyed 355 genetic counselors about their CMF, locus of control orientation, and degree of dispositional optimism. Approximately half of respondents reported they experience CMF; 26.6% had considered leaving their job due to CMF symptoms. Mixed-method analyses revealed that genetic counselors having an external locus of control and low optimism were at highest risk for CMF. Those at highest risk experienced moderate-to-high burnout, low-to-moderate compassion satisfaction, and tended to rely on religion/spirituality when coping with stress. CMF risk was not influenced by years in practice, number of genetic counselor colleagues in the workplace, or completion of graduate training in this area. Recommendations for practice and education are outlined.     

Effects of role model deservingness on overcoming performance deficits induced by stereotype threat

Previous research has shown that exposure to successful role models can restore performance that had been impaired by stereotype threat, and that some role models are more effective than others. The present research examined the effects of role model deservingness on women's mathematics test performance after being placed under stereotype threat. In Experiment 1, a woman who attained success by herself (deserved) proved a more effective role model than an equally likable and successful woman whose success was handed to her (not deserved). In Experiment 2, women role models proved more effective at combating stereotype threat when their successes were attributable to internal‐stable (deserved) than external‐unstable (not deserved) causes, an effect that was partially mediated by reduction in extra‐task thinking. The results are seen as having implications for theories of stereotype threat and causal attribution. Copyright © 2010 John Wiley & Sons, Ltd.     

Can 15-month-old infants understand pretence? An investigation using the 'violation-of-expectation' paradigm

Productive tests are unsuitable for measuring infants' earliest understanding of pretence, because performance demands may render infants unable to produce the actions required to pass the test. Recently, Onishi, Baillargeon and Leslie (2007) used the violation-of-expectation (VOE) paradigm as a measure of infants' understanding of others' pretence that is free from such performance demands. They found that 15-month-old infants looked longer at an Unexpected event in which an actor pretended to pour into one cup but pretended to drink from another cup, compared to pretending to pour and drink with the same cup. On this basis, they argued that 15-month-old infants expect others' pretence to be consistent, demonstrating their understanding of others' pretence. However, infants may have responded to expectations they had about familiar action sequences, rather than to pretence per se. To test this hypothesis, the current study firstly replicated Onishi et al.'s results in a sample of 28 typically developing 15-month-old infants, and then added a condition using closely matched real versions of their pretend VOE tasks. It was found that infants looked longer at unexpected events, whether or not the events were real or pretend. It was concluded that 15-month-old infants may look longer at pretend events due to violations of expectations they have about familiar action sequences, rather than because they understand others' pretence behaviour.     

Spending time: The impact of hours worked on work–family conflict

Scholars have long assumed that as workers spend more time at work fewer hours are available for their non-work lives leading to negative effects in both domains, and most studies examining the impact of work hours on work and life domains have supported this viewpoint. However, the majority of these studies have used one-dimensional measures of work–family conflict (WFC) and family–work conflict (FWC) on homogenous samples which included primarily married managers and professionals with children. Further, despite calls to examine non-linear relationships between work hours and WFC and FWC, few studies have done so. This study uses multi-dimensional measures to examine the linear and non-linear (quadratic) effects of work hours on WFC and FWC in a heterogeneous sample and examines the moderating effects of several work and family characteristics on these relationships. The findings indicate that whereas work hours have a linear relationship with WFC, the relationship between work hours and FWC is curvilinear. Managerial support was found to moderate the relationship between work hours and one dimension of FWC. Number of children moderated the relationships between work hours and WFC and another dimension of FWC.     

Assessing the Role of Spirituality in Coping Among African Americans Diagnosed with Cancer

Spirituality plays an important role in cancer coping among African Americans. The purpose of this study was to report on the initial psychometric properties of instruments specific to the cancer context, assessing the role of spirituality in coping. Items were developed based on a theoretical model of spirituality and qualitative patient interviews. The instruments reflected connections to self, others, God, and the world. One hundred African American cancer survivors completed the instruments by telephone. The instruments showed adequate internal reliability, mixed convergent validity, discriminant validity, and interpretable factor structures.     

A modified counterconditioning procedure prevents the renewal of conditioned fear in rats

Two studies using an ABA design examined the Extinction and renewal of conditioned barpress suppression. Following lights-off and foot shock pairings in Context A, rats were placed in Context B and were given either a standard counterconditioning procedure where the lights-off CS was paired with a novel food US delivered freely or a modified counterconditioning procedure where CS-US pairings only occurred if the rat earned the US by performing a required behavior during the CS. Results indicated that the modified counterconditioning procedure thwarted ABA renewal but the conventional counterconditioning procedure did not reduce ABA renewal any more than nonreinforced exposure to the CS alone. Furthermore, the response required during the modified counterconditioning procedure could be one used as a baseline response during Acquisition of fear or it could be a novel response. Implications of the results for theories of Extinction and renewal of fear are discussed.     

Assessing the Reliability of Situational Judgment Tests Used in High‐Stakes Situations

Assessing reliability of situational judgment tests (SJTs) in high‐stakes situations is problematic with reliability inappropriately measured by Cronbach's alpha when test items are heterogeneous. We computed the corrected, weighted mean alpha from 56 alpha coefficients, which produced a value of α = .46 and reviewed appropriate types of reliability to use with SJTs. In the current longitudinal study, SJT test–retest reliability was r = .82, compared with internal consistency, α = .46, and stratified alpha, α = .45 at Time 1 and α = .52 and stratified α = .51 at Time 2. We used a student sample (Time 1: n = 185; Time 2: n = 132) with items from a credentialing exam with ‘should do’ instructions. The SJT correlated significantly with cognitive ability, r = .30, and agreeableness, r = .24. In Study 2, we assessed test–retest reliability with Human Resource professionals (Time 1: n = 94; Time 2: n = 32) who had been recently credentialed and who participated in a pilot test of new SJT items with ‘most likely/least likely do’ response options. The SJT test–retest reliability was r = .66 compared with internal consistency, α = .43 and stratified α = .47 at Time 1 and α = .61 and stratified α = .67 at Time 2. We discuss the theoretical implications of the Study 1 results as well as the practical implications for use of SJTs in credentialing examinations.     

Social,Religious and Spiritual Capital and Physical/Emotional Functioning in a National Sample of African Americans

Spiritual and religious capital are forms of the broader construct of social capital. The present study, using probability‐based sampling methods, surveyed a national sample of African American adults to examine the relative contributions of spiritual and religious capital to their physical and emotional functioning. Analyses were conducted to determine if these constructs made a unique contribution above and beyond general social capital. African American men and women (N = 803) were interviewed by telephone. Hierarchical linear regressions revealed that, across the full sample, although social capital was a positive predictor of physical and emotional functioning (p < .05 and p < .001), neither religious nor spiritual capital made an additional contribution to these outcomes. However, the relationships among these variables differed for men and women. Among men, social capital predicted positive emotional functioning (p < .001) but not physical functioning; spiritual and religious capital made no additional contribution to either outcome variable. Among women, social capital predicted positive emotional functioning (p < .01) but not physical functioning. However, religious capital did make a significant additional contribution to the prediction of emotional functioning (ΔR², p < .01). Dividing the sample into different age groups did not produce any different findings from those found with the sample as a whole. Findings are discussed in terms of implications for church‐ and faith‐based health promotion interventions aimed at health disparities reduction. Copyright © 2011 John Wiley & Sons, Ltd.     

Environmental enrichment protects against the effects of chronic stress on cognitive and morphological measures of hippocampal integrity

Chronic stress has detrimental effects on hippocampal integrity, while environmental enrichment (EE) has beneficial effects when initiated early in development. In this study, we investigated whether EE initiated in adulthood would mitigate chronic stress effects on cognitive function and hippocampal neuronal architecture, when EE started one week before chronic stress began, or two weeks after chronic stress onset. Adult male Sprague Dawley rats were chronically restrained (6h/d) or assigned as non-stressed controls and subdivided into EE or non-EE housing. After restraint ended, rats were tested on a radial arm water maze (RAWM) for 2-d to assess spatial learning and memory. The first study showed that when EE began prior to 3-weeks of chronic stress, EE attenuated chronic stress-induced impairments in acquisition, which corresponded with the prevention of chronic stress-induced reductions in CA3 apical dendritic length. A second study showed that when EE began 2-weeks after the onset of a 5-week stress regimen, EE blocked chronic stress-induced impairments in acquisition and retention at 1-h and 24-h delays. RAWM performance corresponded with CA3 apical dendritic complexity. Moreover, rats in EE housing (control or stress) exhibited similar corticosterone profiles across weeks, which differed from the muted corticosterone response to restraint by the chronically stressed pair-housed rats. These data support the interpretation that chronic stress and EE may act on similar mechanisms within the hippocampus, and that manipulation of these factors may yield new directions for optimizing brain integrity and resilience under chronic stress or stress related neuropsychological disorders in the adult.     

Agonistic rank,aggression, social context,and testosterone in male pigtail monkeys

Two groups of pigtail monkeys were merged, a third was formed, and individual males were introduced into a group in a series of experiments examining the effects of social context upon agonistic rank, aggressive expression, and testosterone levels. In the first experiment, two heterosexual groups, containing adult males unfamiliar to the other group, were merged. The two groups fought, and the smaller group was defeated. The alpha and beta males of the defeated group were singled out for repeated attack and both showed significant drops in circulating levels of testosterone. Both males were removed from the group during the first day, but testosterone levels did not recover to baseline levels for several days. The alpha male of the victorious group, on the other hand, showed a significant rise in testosterone, which was apparent only on the day following the merger. In order to study the influence of previous social familiarity on male reception into a group, another group was formed by removing males from the victorious group and placing them in a separate enclosure. The males in the new group established a dominance hierarchy unrelated to their previous social ranks with one another. Three months later, each of the six adult males remaining in the parent group was individually introduced into the new group for one day or less. Each of the males introduced into the new group accepted a social position at the lower end of the dominance hierarchy without regard to his previous rank relationships with the host males when they were all in the parent group. Even the alpha and beta males of the parent group were relegated to low rank positions in the new group, despite having ranked over each of the host males since birth. In contrast to the aggression directed at the unfamiliar males in the first experiment, a minimum of aggression was directed to the familiar males introduced into the new group in the second experiment. Although the males introduced accepted low social ranks, it appeared that each was readily integrated into the group with a minimum of aggressive interaction during the time he was scheduled to remain in the group. There were no significant changes in circulating levels of testosterone in any of the males during the introductions of familiar males to one another.
